[0046] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0047] The output gas pressure adjustment method of the ventilator device provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the application environment includes a treatment system, and the treatment system includes a ventilator device and an oxygen concentrator device. Among them, the above-mentioned ventilator device can be configured with a processor and a sensor for monitoring gas characteristic data, and the processor and the sensor can be communicatively connected; the processor and the controller in the oxygen concentrator device can be communicatively connected; the communication method can be Bluetooth, mobile data, Wifi and other connection methods. Optionally, the above-mentioned ventilator device can be, but not limited to, a hybrid drive ventilator, an electric ventilator or a pneumatic ventilator; the above-mentioned oxygen concentrator device can be, but not limited to, a membrane separation oxygen concentrator, a chemical oxygen concentrator or a molecular sieve oxygen concentrator. Optionally, the sensor in the above-mentioned ventilator device can monitor the output gas flow and output gas pressure of the ventilator device. The following embodiment of the present application uses the processor in the ventilator device as the execution subject to introduce the specific process of the operating parameter compensation method.

[0048] In an exemplary embodiment, Figure 2 As shown, a method for adjusting the output gas pressure of a ventilator device is provided. The method is described by taking the application of the method to a processor in a ventilator device as an example. The method can be implemented by the following steps:

[0049] S100: When the ventilator device is in working state, obtain the output gas flow and output gas pressure of the ventilator device.

[0050] Among them, when the ventilator device is in working state, the sensor in the ventilator device can monitor the output gas flow and output gas pressure of the ventilator device at each moment in real time. Correspondingly, the processor in the ventilator device can obtain the output gas flow and output gas pressure of the ventilator device sent by the sensor.

[0051] It should be noted here that when the ventilator device is in working condition, the ventilator device can receive oxygen input from the oxygen concentrator device and mix the air and oxygen before outputting them, that is, the gas output by the ventilator device is a mixed gas.

[0052] S200 , determining an output gas pressure change of the ventilator device to be compensated per unit time based on the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user.

[0053] In practical applications, the current user may be a user experiencing obstructive sleep apnea; the current user's output gas flow rate may be understood as the current user's expiratory flow rate, and the current user's output gas pressure may be understood as the current user's expiratory pressure. Optionally, the output gas pressure change of the ventilator device to be compensated per unit time may be understood as the output gas pressure of the ventilator device that needs to be compensated to bring the output gas pressure of the ventilator device within the ideal range.

[0054] Among them, the output gas flow and output gas pressure of the above-mentioned current user can be obtained by detecting through a gas parameter detector, and the gas parameter detector is communicated with the ventilator device to send the output gas flow and output gas pressure of the current user to the ventilator device.

[0055] Specifically, at each moment, the processor in the ventilator device can obtain the output gas flow and output gas pressure of the current user, and determine the output gas pressure change of the ventilator device to be compensated per unit time based on the output gas flow and output gas pressure of the ventilator device, as well as the output gas flow and output gas pressure of the current user.

[0056] In one embodiment, the processor can pre-train an algorithm model, and then input the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user into the algorithm model, and the algorithm model outputs the output gas pressure change of the ventilator device to be compensated per unit time.

[0057] In another embodiment, the processor can also perform conversion processing, analysis processing, comparison processing and other operations based on the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user, and determine the output gas pressure change of the ventilator device to be compensated per unit time based on the processing operation results.

[0058] S300: Adjust the pressure of the output gas of the ventilator device based on the change in the output gas pressure.

[0059] The output gas pressure variation of the ventilator device can be positive or negative. Specifically, the processor in the ventilator device can adjust the output gas pressure of the ventilator device based on the output gas pressure variation according to a preset pressure adjustment strategy.

[0060] In addition, the processor in the ventilator device can also determine the adjustment frequency of the ventilator device's output gas pressure based on the output gas pressure change, and adjust the ventilator device's output gas pressure according to the adjustment frequency.

[0061] S400: According to the adjusted pressure of the output gas of the ventilator device, the pressure of the output gas of the ventilator device is adjusted by using a curve pressure boosting method.

[0062] In actual applications, at any moment, the processor in the ventilator device can first obtain the current output gas pressure of the ventilator device obtained after adjustment in the previous steps, and input the curve boost mark and the current output gas pressure of the ventilator device into a pre-trained adjustment pressure value determination model. The adjustment pressure value determination model uses the curve boost method to determine the adjustment pressure value at the current moment, and then adjusts the output gas pressure of the ventilator device according to the adjustment pressure value.

[0063] Optionally, the above-mentioned adjusted pressure value determination model can be implemented by at least one of a convolutional neural network model, a fully connected neural network model, a long short-term memory neural network model, a residual neural network model, etc.

[0064] In addition, the processor in the ventilator device can call the curve boost adjustment tool, and then input the current output gas pressure of the ventilator device obtained after adjustment in the previous steps into the curve boost adjustment tool. The curve boost adjustment tool outputs the pressure of the output gas of the ventilator device using the curve boost method according to the current output gas pressure of the ventilator device.

[0065] In actual application, after the ventilator device stops working and then starts working again, the output gas pressure of the ventilator device can be adjusted according to the previous adjustment method, and the steps in S100-S400 above can be performed based on the adjustment results. In particular, if the output gas pressure of the ventilator device can reach the ideal range after adjusting the output gas pressure of the ventilator device according to the previous adjustment method, there is no need to repeat the steps in S100-S400 above, which can save adjustment time and speed up the adjustment process.

[0066] The technical solution in the embodiment of the present application is to obtain the output gas flow and output gas pressure of the ventilator device when the ventilator device is in working state, determine the output gas pressure change of the ventilator device to be compensated per unit time based on the output gas flow and output gas pressure of the ventilator device, and the output gas flow and output gas pressure of the current user, adjust the pressure of the output gas of the ventilator device based on the output gas pressure change, and adjust the pressure of the output gas of the ventilator device by using a curve boosting method according to the pressure of the output gas of the ventilator device after adjustment; the above method can adjust the output gas pressure of the ventilator device through two adjustments, improve the rationality of the output gas pressure adjustment of the ventilator device, thereby improving the accuracy of the output gas pressure adjustment of the ventilator device, and the secondary adjustment of the output gas pressure of the ventilator device by using a curve boosting method can make the pressure increase of the output gas of the ventilator device more gentle and less volatile, thereby improving the stability of the adjustment process.

[0067] The following describes the process of determining the output gas pressure change of the ventilator device to be compensated per unit time based on the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user. Figure 3 As shown, the steps in S200 above can be implemented in the following ways:

[0068] S210. Preprocess the output gas flow and output gas pressure of the ventilator device respectively to obtain a first gas flow and a first gas pressure; and preprocess the output gas flow and output gas pressure of the current user respectively to obtain a second gas flow and a second gas pressure.

[0069] In practical applications, the processor in the ventilator device may pre-process the output gas flow of the ventilator device to obtain the first gas flow, and pre-process the output gas pressure of the ventilator device to obtain the first gas pressure.

[0070] At the same time, the processor in the ventilator device can pre-process the output gas flow of the current user to obtain the second gas flow, and pre-process the output gas pressure of the current user to obtain the second gas pressure.

[0071] Optionally, the above preprocessing can be at least one of denoising, outlier removal, normalization, standardization, logical analysis, etc. The denoising method can be but is not limited to wavelet transformation, filtering and / or feature screening.

[0072] S220 : Determine an output gas pressure change according to the first gas flow rate, the first gas pressure, the second gas flow rate, and the second gas pressure.

[0073] In one implementation, at any moment, the processor may perform an arithmetic operation on the first gas flow rate, the first gas pressure, the second gas flow rate, and the second gas pressure to obtain a change in the output gas pressure. Optionally, the arithmetic operation may be at least one of addition, subtraction, multiplication, division, logarithm, and exponential operation.

[0074] In another implementation, at any moment, the processor can pre-train an algorithm model, and then input the first gas flow, the first gas pressure, the second gas flow, and the second gas pressure into the algorithm model, which outputs the output gas pressure change to be compensated by the ventilator device per unit time.

[0075] In one embodiment, if Figure 4 As shown, the step of determining the output gas pressure change according to the first gas flow rate, the first gas pressure, the second gas flow rate, and the second gas pressure in the above S220 can be implemented by the following method:

[0076] S221. Obtain a pressure difference between the first gas pressure and the second gas pressure.

[0077] In an embodiment of the present application, the processor in the ventilator device can perform a differential operation on the first gas pressure and the second gas pressure to obtain the pressure difference between the first gas pressure and the second gas pressure.

[0078] S222: Determine the output gas pressure change according to the pressure difference, the first gas flow rate, the Fourier transform result of the second gas flow rate, and the Fourier transform result of the first gas pressure.

[0079] Furthermore, the processor can perform Fourier transform processing on the second gas flow to obtain the Fourier transform result of the second gas flow, and perform Fourier transform processing on the first gas pressure to obtain the Fourier transform result of the first gas pressure, and perform arithmetic operation on the pressure difference, the first gas flow, the Fourier transform result of the second gas flow and the Fourier transform result of the first gas pressure to obtain the output gas pressure change of the ventilator equipment to be compensated per unit time.

[0080] Alternatively, the processor can also process the pressure difference, the first gas flow, the Fourier transform results of the second gas flow and the Fourier transform results of the first gas pressure according to a preset processing method to obtain the output gas pressure change of the ventilator device to be compensated per unit time.

[0081] In the embodiment of the present application, the processor can determine the output gas pressure change using the following formula (1) based on the pressure difference, the first gas flow rate, the Fourier transform result of the second gas flow rate, and the Fourier transform result of the first gas pressure, namely:

[0082] (1)

[0083] (2)

[0084] in, express The output gas pressure change of the ventilator equipment at any moment, express The output gas pressure of the ventilator equipment at all times, The output gas pressure of the current user at the moment, express The output gas flow of the current user at the moment, express The output gas flow of the ventilator equipment at all times, Represents the scale factor.

[0085] It should be noted here that the output gas pressure of the ventilator equipment is adjusted in real time as time changes.

[0086] The technical solution in the embodiment of the present application pre-processes the output gas flow and output gas pressure of the ventilator device respectively to obtain a first gas flow and a first gas pressure; and pre-processes the output gas flow and output gas pressure of the current user respectively to obtain a second gas flow and a second gas pressure, and determines the output gas pressure change according to the first gas flow, the first gas pressure, the second gas flow and the second gas pressure; in the process of determining the output gas pressure change of the ventilator device per unit time according to the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user, the above method first pre-processes the output gas flow and the output gas pressure, which can improve the accuracy of the output gas pressure change finally obtained and provide reliable reference information for subsequent processing.

[0087] The following describes the process of adjusting the pressure of the output gas of the ventilator device based on the output gas pressure change. Figure 5 As shown, the steps in the above S300 may include:

[0088] S310: Determine the adjusted pressure of the output gas of the ventilator device according to the output gas pressure change and the output gas pressure of the ventilator device.

[0089] In an embodiment of the present application, the processor in the ventilator device can add the output gas pressure change and the output gas pressure of the ventilator device to obtain the adjusted pressure of the output gas of the ventilator device.

[0090] S320: Control the ventilator device to output gas according to the adjusted pressure, so as to adjust the pressure of the gas output by the ventilator device.

[0091] Furthermore, the processor may control the ventilator device to adjust the pressure so as to adjust the pressure of the gas output by the ventilator device.

[0092] In one embodiment, if Figure 6 As shown, the step of adjusting the pressure of the output gas of the ventilator device by using a curve pressure boosting method according to the pressure of the output gas of the ventilator device after adjustment in S400 may include:

[0093] S410 , determining the pulse pressure of the output gas of the ventilator device according to the preset curve pressure increase adjustment strategy and the adjusted pressure of the output gas of the ventilator device.

[0094] In practical applications, at any given moment, the processor in the ventilator device can pre-train an algorithm model, then input the adjusted pressure of the ventilator device's output gas and the curve pressure increase adjustment strategy into the algorithm model, and the algorithm model outputs the pulse pressure of the ventilator device's output gas. Optionally, the pulse pressure of the ventilator device's output gas can be understood as the gas pressure output by the ventilator device in the form of pulses. It should be noted here that the adjusted pressure of the ventilator device's output gas can be understood as the pressure of the ventilator device's output gas after a single adjustment.

[0095] In an embodiment of the present application, the processor in the ventilator device can also directly adjust the adjusted pressure of the ventilator device output gas according to a preset curve boost adjustment strategy to obtain the pulse pressure of the ventilator device output gas.

[0096] Optionally, the above curve boost adjustment strategy can be expressed by the following formula (3):

[0097] t (3)

[0098] in, express The pulse pressure of the gas output by the ventilator at all times, express The output gas pressure change of the ventilator equipment at any moment, 、 are different proportional coefficients. For example, Figure 7 Shown is a graph of the pulse pressure of the gas output by the ventilator device over time.

[0099] S420: Control the pressure of the gas output by the ventilator device according to the pulse pressure output of the gas output by the ventilator device to adjust the pressure of the gas output by the ventilator device.

[0100] Furthermore, at any moment, the processor can control the pressure of the gas output by the ventilator device at that moment, and output the gas according to the pulse pressure of the gas output by the ventilator device at that moment, so as to adjust the pressure of the gas output by the ventilator device at that moment.

[0101] It should be noted here that the adjustment of the ventilator device output gas pressure at any moment will affect the ventilator device output gas pressure at the next moment. Naturally, the ventilator device output gas pressure adjustment process in the embodiment of the present application can be understood as a feedback adjustment process.

[0102] The technical solution in the embodiment of the present application can adjust the output gas pressure of the ventilator device through two adjustments, thereby improving the rationality of the adjustment of the output gas pressure of the ventilator device, thereby improving the accuracy of the adjustment of the output gas pressure of the ventilator device, and using a curve boosting method for the second adjustment to achieve smooth adjustment. Overall, it can improve the stability of the adjustment results of the output gas pressure of the ventilator device.

[0103] In some scenarios, the steps in S100-S400 above need to be executed under specific triggering conditions. The following describes the process. In one embodiment, before executing the steps in S100 above, Figure 8 As shown, the above method may further include:

[0104] S500: Perform identification processing based on the output gas flow and output gas pressure of the current user to determine the apnea state of the current user.

[0105] In actual applications, the processor in the ventilator device can input the current user's output gas flow and output gas pressure into a pre-trained apnea recognition model. The apnea recognition model performs recognition processing based on the current user's output gas flow and output gas pressure and then outputs the current user's apnea status.

[0106] In addition, the processor in the ventilator device can also use an apnea algorithm to identify and process the current user's output gas flow and output gas pressure to determine the current user's apnea state.

[0107] S600: When the apnea state is yes, executing the step of obtaining the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user.

[0108] Furthermore, when it is determined that the apnea state is yes, the steps in S100 are started.

[0109] The technical solution in the embodiment of the present application determines the apnea state of the current user by identifying and processing the output gas flow and output gas pressure of the current user, and when the apnea state is yes, executes the steps of obtaining the output gas flow and output gas pressure of the ventilator device and the output gas flow and output gas pressure of the current user; the above method can determine whether the triggering conditions for output gas pressure adjustment are met before adjusting the output gas pressure of the ventilator device, so as to avoid excessive adjustment and the occurrence of unreasonable adjustment results, and this process can also effectively save the adjustment time of the output gas pressure of the ventilator device and reduce the power consumption of the ventilator device.

[0110] In one embodiment, the present application also provides a method for adjusting the output gas pressure of a ventilator device, which is applied to a processor in a ventilator device in a treatment system. The method includes the following process:

[0111] (1) When the ventilator is in working condition, the user's apnea state is determined based on the output gas flow and output gas pressure of the current user;

[0112] (2) When the apnea state is yes, obtain the output gas flow and output gas pressure of the ventilator device;

[0113] (3) pre-processing the output gas flow and output gas pressure of the ventilator device to obtain a first gas flow and a first gas pressure; and pre-processing the output gas flow and output gas pressure of the current user to obtain a second gas flow and a second gas pressure;

[0114] (4) obtaining a pressure difference between the first gas pressure and the second gas pressure;

[0115] (5) Determine the output gas pressure change of the ventilator device to be compensated per unit time based on the pressure difference, the first gas flow rate, the Fourier transform result of the second gas flow rate, and the Fourier transform result of the first gas pressure;

[0116] (6) Determine the adjusted pressure of the output gas of the ventilator device based on the output gas pressure change and the output gas pressure of the ventilator device;

[0117] (7) Control the ventilator equipment to output gas according to the adjusted pressure;

[0118] (8) Determine the pulse pressure of the ventilator output gas according to the preset curve boost adjustment strategy and the adjusted pressure of the ventilator output gas;

[0119] (9) Control the pressure of the gas output by the ventilator device, and output the gas according to the pulse pressure of the gas output by the ventilator device to adjust the pressure of the gas output by the ventilator device.

[0120] The execution process of the above (1) to (9) can be specifically referred to the description of the above embodiment. The implementation principles and technical effects are similar and will not be repeated here.
